A.5.1 Configuration Example
A.5.1 Configuration Example
This section gives a configuration example in which a SPARC M10-4S with a SPARC64 X+ processor mounted is added to the physical partition configured with one SPARC M10-4S with a SPARC64 X processor mounted. This enables active replacement of each SPARC M10-4S.
To enable active replacement of the SPARC M10-4S with PPAR DR, the configuration must satisfy the following conditions.
To enable active replacement of the SPARC M10-4S with PPAR DR, the configuration must satisfy the following conditions.
- It is necessary to create a redundant configuration by connecting I/O devices under the root complex on each SPARC M10-4S to the system volume I/O devices and the network of the control domain. This is done for the following reasons: When a SPARC M10-4S is removed, the I/O devices for the remaining SPARC M10-4Ss can be used to continue the operation even if an I/O configuration change is done by restarting the control domain.
- It is necessary to divide root domains for each SPARC M10-4S. This is done for the following reasons: When a SPARC M10-4S is removed, the status whereby it is impossible to use services provided by the physical I/O devices of other SPARC M10-4Ss must be avoided.
- It is necessary to operate the business with a guest domain consisting of virtual I/O devices (vdisk, vnet). This is done for the following reasons: The root domain is stopped at SPARC M10-4S removal and the physical I/O devices can be disconnected. Moreover, these operations will not influence the guest domain that is performing the operation.

*1 A memory region of approx. 2 GB or 1.25 GB on each SPARC M10-4S is assigned for the hypervisor. So, the memory resource that can be assigned to the logical domain is smaller than the physically mounted memory capacity. |
